                    <li class="wide"><strong>Work with huge files.</strong>&nbsp;&nbsp;Hex Fiend can handle as big a file as you’re able to create.  It’s been tested on files as large as 118 GB.</li>
                    <li class="wide"><strong>Small footprint.</strong>&nbsp;&nbsp;Hex Fiend does not keep your files in memory.  You won’t dread launching or working with Hex Fiend even on low-RAM machines.</li>
                    <li class="wide"><strong>Fast.</strong>&nbsp;&nbsp;Open a huge file, scroll around, copy and paste, all instantly.  Find what you’re looking for with fast searching.</li>
                    <li class="wide"><strong>Binary diff.</strong>&nbsp;&nbsp;Hex Fiend can show the differences between files, taking into account insertions or deletions.</li>
                    <li class="wide"><strong>Smart saving.</strong>&nbsp;&nbsp;Hex Fiend knows not to waste time overwriting the parts of your files that haven’t changed, and never needs temporary disk space.</li>
                    <li class="wide"><strong>Data inspector.</strong>&nbsp;&nbsp;Interpret data as integer or floating point, signed or unsigned, big or little endian...</li>
                    <li class="wide"><strong>Embeddable!</strong>&nbsp;&nbsp;It’s really easy to incorporate Hex Fiend’s hex or data views into your app.  Its permissive BSD-style license won’t burden you.</li>
